VVThis 'invention relates toan impmvedA turntable particularly adapted jfor yuse'vwith phonographs of theportable'type. g

An object ofthe invention is to'provide` a simple,Y efiicient,` strong, durable 'turntable which can be very econoi'nically.l manufactuned and 'used in connection'with a portable phonographV to support discs of. -standard when not in use to occupy avery small area,

so ,that it will lie well within the area defined vby the box and the cover which usuallycon-V tain aportablephonograph.Y Y

They invention is illustrated inthedrawings, of which Figure 1 is a'plany view. of

fthe topv of a phonograph box showing' the..`v

'f turntable, Athe supporting leaves of which are shown in* their inoperativefpositionsjinH l fullline and are shown 1n positions yin :dotted lines. j

In vits general aspect the inventionzcom-ff prises a rotatable plate of a small diameter.;A

' j which canbe mounted in associationl with a rotating shaft extendingl above the topofr a box. On this plate orldisc Ijmount a plurality of pivoted leaves which, when swung outwardly Vwill extend beyond the area ofthe diseV` to act vas supporting sur-- faces for phonograph records, thus increasing thev natural inherent supporting ,capacity ofthe discrit'self. The disc is providedwith suitable stop :pins adjacent the pivoted points of the leaves lto limit. their' outward- 1 movementso thatfthey' cannot vbe moved beyond the point of maximumradius. This.` will insurethe proper positioning o'fftheA leaves.` Preferably theleaves are `provided with suitable cushioning covering such as felt toenablewthem to make contact with the articles to'be supported' and to properly..`

gripy them without injury.

In the preferred form of the `invention Vprovide a phonographhaving a top plate 10 through which they upper endV 11- of, a rotatable shaft extends. The shaft; is pro-` V vided with a transverse pin 12 toibe engaged byafgroovel formed in a hub 141,A attached .to a 'disc' or platel 15. This discorV platef 15 is provided with a plurality of leaves 16, I

preferably sector shaped and inthe form theiroperative'V of alrfrplate' to fthe 15,v at

symmetrically placed-pjoints around itscir.-V y

ldisc bymeans of'rivets 18. These lea-ves are adapted Vto :be swung outwardly, vfas shown in dotted lines in Figure ,1,v sofas lto cumference` preferably nearthe edges ofthe f' .Y disc.'v Each of theseleaves iscovered-'with f suitable-cushioning material such. as felt 1 7. The leaves are preferably pivoted.` to` the' increase the normal supporting radiusfoff thedisc 15. vStop pins 19 arel disposedadjacent the-pivot. points oftheleaves, :so that when the leaves areswungoutwardly their edges will encounter these stop pins to limit their, further movement. x v

outwardly yuntil their further movement is interrupted by the pins 19, Theirv radius vin this' extended position will vpermit records ofwstandard size yto be supportedl thereby.

wardly 'tothe position shown in full lines vwhich therefore yinsures anxorderly assem- -blage of the leaves 16. The Vcushioning cover on -the'leaves permits .the records to surface thereof. M
